Your class isn't doing a review together for it? OR are you not in the class? I'm sure your teacher has old tests they could give you to look at and work. All the multiple choice sections through 1998 are released and all free answer sections are released. My teacher has all the tests since like 1957. :Q

For the basics, read your textbook. Best way to do it, no doubt. Review guides like Princeton and such are good but only if you already have a pretty good grasp of the material. Good for reviewing, but not for learning from scratch.

Don't be a cheap ass. That test costs $80. $20-$30 spent on study aides is nothing.

If you have lots of time to study and you don't feel at all confident about your calc skills, I'd say get the Barrons *and* the Princeton Review study guides (more practice problems). If you've got the basics down, just get one then; they're both pretty good. They have very simple explanations that you can follow along. I only took Calculus AB, and with the help of the Princeton Review study guide (my calc teacher flat out refused to help me, that bitch), I was able to learn the additional BC topics well enough to get a 5.
